Adjusting the Projection Distance
Setup
• Refer to pages 33 and 34 about the function of Keystone correction and placement of projector using the
correction.
• Decide the placement of the projector referring to the figures on the table and the diagram below
according to the size of your screen and input signal.

(a) Maximum projection distance
(b)Minimum projection distance
(c) Horizontal placement range when projection distance is maximum.
(d)Horizontal placement range when projection distance is minimum.
(e) Vertical placement range when projection distance is maximum.
(
f) Vertical placement range when projection distance is minimum.
Note
• The aspect ratio of the projected image shifts slightly when
the lens shift is at a position other than the top position.
• The aspect ratio of the projected image also shifts slightly
when the “H Keystone” and “V Keystone” functions are
adjusted simultaneously.
• When adjusting “H Keystone” and “V Keystone” at the same
time, the values of adjustable angles for each setting
become smaller.
• Keystone correction cannot be applied to On-screen
Display.
• When Keystone correction is applied, the resolution of image
can be deteriorated to some extent.
• There are errors of ±3% in the formulas below.
